在入射能量为420 MeV的情况下，对双β衰变核Xe进行了（）电荷交换反应实验，目的是测量Cs中的Gamow-Teller（GT）强度分布。测量已经进行了色散匹配WS束线和大雷电光谱仪的核物理研究中心在大坂，在那里实现了42千电子伏的能量分辨率。一种新的气体电池与薄窗口制成的聚萘二甲酸乙二醇酯已被用作目标。提取的GT强度分布面临着相当长的衰变半衰期。
A () charge-exchange reaction experiment on the double-beta decaying nucleusXe has been performed at an incident energy of 420 MeV with the objective to measure the Gamow-Teller (GT) strength distribution inCs. The measurements have been carried out at the dispersion-matched WS beam line and the Grand Raiden spectrometer of the Research Center for Nuclear Physics in Osaka, where an energy resolution of 42 keV was achieved. A new gas cell with thin windows made of polyethylene naphthalate has been employed as a target. The extracted GT strength distribution is confronted with the rather longdecay half-life ofXe.
